searchView是一个为用户提供输入搜索查询和提交请求给搜索提供者的用户界面部件，显示查询建议或结果列表！本篇介绍一下将searchView加入到自定义标题栏布局中，结合listview实现搜索，首先看一下自定义布局：

1.自定义标题栏布局：custom_action_bar_layout.xml

android:id="@+id/search_view"
android:layout_width="0px"
android:layout_height="match_parent"
android:layout_weight="1"
android:iconifiedByDefault="false"
android:inputType="textFilter"
android:queryHint="@string/title_search_hint" >

2.主页布局：activity_main.xml ：

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >

android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#969696" />

3. MainActivity.java

package com.example.searchview2;

import java.util.ArrayList;

import android.app.ActionBar;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.text.TextUtils;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.SearchView;

public class MainActivity extends Activity implements
SearchView.OnQueryTextListener {
ListView listView;
SearchView searchView;
Object[] names;
ArrayAdapter adapter;
ArrayList mAllList = new ArrayList();

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initActionbar();
names = loadData();
listView = (ListView) findViewById(R.id.list);
listView.setAdapter(new ArrayAdapter
